Seabridge Gold Targets High-Grade In New KSM Drilling Program Aims To Build High-Grade Resource In Newly Identified Structure At Sulphurets

Toronto, Canada... Seabridge Gold (TSX: SEA, NYSE:SA) announced today that drilling has begun on the KSM project designed to off-set and extend high-grade gold intersections discovered in previous drilling. Two core rigs have been mobilized to complete 4,000 meters in 16 shallow holes within the proposed pit of the Sulphurets Deposit (see map). The $2.5 million program is expected to be completed before the first of October.  

Seabridge Chairman and CEO Rudi Fronk commented: "Our original plans for this year at KSM were focused on completing geophysical surveys to help refine the limits of the existing four porphyry deposits and look for a fifth. A concept to expand the 1500 g/t intersection drilled last year grew out of these surveys and the target was too compelling to ignore. This new target is within the proposed Sulphurets pit plan, so if the program is successful, we will immediately capture new resources."

During 2018, waste characterization and geotechnical drilling of the proposed Sulphurets pit encountered high grade gold intersections in the following holes:

• S-18-81: from 69.0 to 71.0 meters, 2.0 meters of 1580.0 g/t Au (>50 oz/tonne) and 209.0 g/t Ag
• S-18-82: from 21.0 to 33.2 meters, 12.2 meters of 5.8 g/t Au and 7.2 g/t Ag as well as from 112.0 to 116.0 meters, 4.0 meters of 18.5 g/t Au and 30.6 g/t Ag
• S-18-83: from 117.0 to 119.0 meters, 2.0 meters of 4.4 g/t Au and 3.0 g/t Ag

The table at the end of this news release contain the intersections that were previously reported for these three holes.

After reviewing the above results, additional shallow intersections were identified from previous drill campaigns in the same area, including:

• S-11-70: from 151.2 to 153.5 meters, 2.3 meters of 19.6 g/t Au and 5.8 g/t Ag.
• MC-05-03: from 120.0 to 122.0 meters, 2.0 meters of 9.2 g/t Au and 7.5 g/t Ag.

These intersections are clustered within a newly-identified northeast to southwest trending structure having at least 800 meters of strike length. The true width of this zone has not been fully assessed; this program is required to confirm mineralized widths. High-grade gold in these intersections is associated with veins that contain chlorite, biotite and abundant pyrite and visible gold. An Induced Polarization survey conducted over this area has confirmed the structural trend while interpretation of the data continues. Expectations are that this epithermal-style structure consists of anastomosing veins with abundant pyrite and localized zones of high-grade gold. Successful delineation of this target would have a positive impact on the Sulphurets resource since the pit block model currently classifies this area as waste.

Exploration activities by Seabridge at the KSM Project are being conducted under the supervision of William E. Threlkeld, Registered Professional Geologist, Senior Vice President of Seabridge and a Qualified Person as defined by National Instrument 43-101. Mr. Threlkeld has reviewed and approved this news release. An ongoing and rigorous quality control/quality assurance protocol is employed in all Seabridge drilling campaigns. The sampling program, analyzed at ALS Global, includes blank, duplicates and reference standards, with all copper assays that exceed 0.25% Cu re-analyzed using ore grade analytical techniques. Cross-check analyses are conducted at a second external laboratory, Bureau Veritas Laboratories, on at least 10% of the drill samples.

Seabridge holds a 100% interest in several North American gold projects. Seabridge's principal assets are the KSM Project and Iskut Project located near Stewart, British Columbia, Canada, the Courageous Lake gold project located in Canada's Northwest Territories and Snowstorm in the Getchell Gold Belt of Northern Nevada.
